STR3A155 - PWM Off-Line Switching Regulator ICs

STR3A100 series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC in one package. Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectivene.

STR3A155 Features

* Current mode PWM control

* Built-in Random Switching function: reduces EMI noise, simplifies EMI filters, and cuts cost by external part reduction

* Built-in Slope Compensation function: avoids subharmonic oscillation

* Built-in Leading Edge Blanking (LEB) function
